Two recent developments (and I’m only slightly bitter
that I had to find out with the rest of the common people).

The FTA’s
revised Transit Noise and Vibration Impact Assessment
guidance manual has been released. Biggest changes seem to be
the inclusion of train horns/whistles into the noise analysis and revised
vibration critieria for detailed analyses. Available
here or
here.

My favorite
microphone manufacturer has released a new
microphone designed for use
in a Blumein configuration using a custom mount. Just in time for
AES San Francisco! While you’re checking out the mics,
you should also check Soundwave Research’s blog - lots of great info about acoustic design,
manufacturing challenges, medical devices, history, and Bob Crowley’s unusual,
err, esoteric hobbies.
(just kidding Bob, the recorder cum shakuhachi sounded great!).
